Adhesives for leather and footwear materials - Preparation of bonded test pieces by moulding-on processes
This European Standard specifies procedures for the preparation of test pieces comprising adhesive coated leather or other footwear upper material onto which a soling material is moulded directly. The procedures described simulate direct vulcanising of rubber, injection moulding of thermoplastics and reaction moulding of polyurethane.
The prepared test pieces are suitable for the test procedures described in EN 1392, to meet the requirements of EN 15307.

Lepila za usnjene in obutvene materiale - Izdelava lepljenih preskušancev s postopki direktnega podplatenja
Ta evropski standard določa postopke za pripravo preskušancev, ki vključujejo z lepilom prevlečeni usnjeni ali drug obutveni zgornji material, na katerega se neposredno vlije material za podplate. Opisani postopki posnemajo neposredno vulkanizacijo gume, podplatenje plastomerov z nabrizgavanjem in reakcijsko podplatenje poliuretana. Da pripravljeni preskušanci ustrezajo zahtevam v EN 15307, morajo biti primerni za preskusne postopke, opisane v EN 1392. IZJAVA O VARNOSTI – Kjer je to primerno, morajo biti osebe, ki uporabljajo ta dokument, seznanjene z običajnimi laboratorijskimi praksami. Ta dokument nima namena obravnavati vseh varnostnih problemov, ki bi lahko bili povezani z njegovo uporabo. Odgovornost uporabnika je, da vzpostavi primerne varnostne in zdravstvene prakse in zagotovi skladnosti z vsemi zakonskimi pogoji. OKOLJSKA IZJAVA – Razume se, da imajo nekateri materiali, ki jih dovoljuje ta standard, lahko negativen učinek na okolje. Ko bo tehnološki napredek omogočil sprejemljive alternative za te materiale, bodo v največji mogoči meri izločeni iz tega standarda. Ob koncu preskusa mora uporabnik standarda poskrbeti, da odstrani odpadke na primeren način, v skladu z lokalnimi predpisi.

Introduction EN 15307 and EN 1392 specify methods of testing and evaluation of adhesives for leather and footwear materials in "stuck-on" assemblies. Most footwear produced in Europe is manufactured using stuck-on processes, but a significant proportion is produced by "moulding-on" processes such as vulcanising, injection moulding and reaction moulding. This document specifies the preparation of bonded test pieces by moulding-on processes. The form and dimensions of the test pieces produced allows testing according to the test methods specified in EN 1392, and evaluation of the bond strength obtained according to EN 15307. This document therefore complements the above mentioned series of documents, and together they allow the simulation, testing and evaluation of almost all bonds occurring in common footwear constructions.
